What should you start with if polishing is required?

• A. Coarsest grit
• B. Medium grit
• C. Any grit
• D. As fine of grit as possible

Answer: (D)

Polishing is about refining the surface to a smooth, reflective finish, so you want to begin with the finest abrasive that will still effectively remove the last imperfections. Starting with a very fine grit minimizes introducing new scratches and allows a uniform, bright surface as you finish. If you start with a coarser grit, you’d create scratch patterns that are harder to erase in the final polish, requiring more steps to achieve the same smooth result. In practice, you’d typically remove major flaws with coarser grits earlier, then use progressively finer abrasives ending with the finest possible finish to achieve the polish. If only minor blemishes remain, beginning with the finest grit makes the polishing process most efficient and yields the best look.
